I’m sorry, but what you’re saying simply is not true. It’s immensely frustrating. Using bing, DDG, or literally any other search engine doesn’t have this problem. And I’m searching common words, common concepts, basic things that even the worst search engines will accurately provide results for.
The most frustrating thing is sometimes the language will flip. I will get English on certain hours of the day. But if I make a single search in Japanese, it flips back into that mode and there’s no unsticking it.
